Sulfasalazine Immunology & Inflammation related Inibitore

N. Cat.: S1576

La Sulfasalazine è un derivato sulfonamidico della mesalazina, utilizzata come agente antinfiammatorio per trattare le malattie intestinali e l'artrite reumatoide. Questo composto è un potente e specifico inibitore del fattore nucleare kappa B (NF-κB), del TGF-β e della COX-2. Induce ferroptosis, apoptosis e autophagy.

NF-κB
COX-2
TGF-β
In vitro

Sulfasalazine, like methotrexate, enhances adenosine release at an inflamed site and that adenosine diminishes inflammation via occupancy of A2 receptors on inflammatory cells. This compound treatment for 4 hours inhibits kappaB-dependent transcription with an IC50 value of approximately 0.625 mM. This chemical (2.5 mM) results in cell death of T-lymphocytes in a dose- and time-dependent manner. This compound but not 5ASA or sulfapyridine, strongly inhibits NF-kappaB activation and potently induces apoptosis in T-lymphocytes. It is cleaved into sulfapyridine and 5-aminosalicylic acid (5-ASA; mesalamine) by colonic bacteria, and the latter, too, is reported to suppress NF-kappaB activity. This compound but not its cleaved form 5-ASA causes a dose-dependent inhibition of glioma growth, this effect is entirely attributable to the inhibition of cystine uptake via the system x(c)(-) cystine-glutamate transporter. It inhibits cystine uptake causing a chronic depletion of intracellular GSH and consequently compromised cellular redox defense which stymied tumor growth.

In vivo

Sulfasalazine markedly decreases the number of leukocytes that accumulated in the inflamed (carrageenan, 2 mg/ml) air pouch in the murine air pouch model of inflammation. This compound treatment promotes a marked increase in splenocyte 5-aminoimidazole-4-carboxamidoribonucleotide (AICAR) concentration, which is consistent with the in vitro observation that it inhibits AICAR transformylase.
